Product Details
High-precision aluminum profiles are among the industrial aluminum profiles.One of the categories with the highest technical requirements. Its core difference from ordinary industrial profiles lies in:Dimensional tolerances, geometric tolerances, and stress control must all meet precision standards..
As fields such as semiconductor equipment, optical testing instruments, and precision automation equipment develop towards high precision, the precision requirements for aluminum profiles are becoming increasingly stringent.Micron-level dimensional deviation, long-term stable dimensional retention, and extremely low stress release.None of them are indispensable.
Shanghai Chuansi Aluminum focuses onHigh-precision aluminum profile mold opening and customizationFrom mold design and simulation, ultra-high-precision profile extrusion (cooperative production line) to CNC precision machining and ultimate stress relief treatment, the entire process is independently controllable.

04 Ultimate stress relief treatment – eliminating precision drift
High-precision profiles are the most fearedaccuracy drift—The residual stress inside the profile gradually releases during long-term use, leading to a decrease in equipment accuracy.
Adopt"Quenching + two-stage aging + cryogenic treatment + natural aging"Ultimate stress relief process:
| process step | effect |
|---|---|
| quenching | Solid solution strengthening ensures material performance |
| two-stage aging | Fully release internal stress generated by extrusion and heat treatment |
| cryogenic treatment | Eliminate residual austenite and stabilize the microstructure |
| natural aging | Stable processing before shipment ensures long-term dimensional stability. |
Internal stress levels are far below industry standards.The deformation of the profile after precision machining is extremely small. It maintains stable dimensions under constant temperature conditions for extended periods, preventing equipment accuracy drift caused by stress release.
